How ancient skepticism can help you attain tranquility by learning to suspend judgment. 

Along with Stoicism and Epicureanism, Skepticism is one of the three major schools of ancient Greek philosophy that claim to offer a way of living as well as thinking. "How to Keep an Open Mind" provides an unmatched introduction to skepticism by presenting a fresh, modern translation of key passages from the writings of Sextus Empiricus, the only Greek skeptic whose works have survived. While content in daily life to go along with things as they appear to be, Sextus advocated-and provided a set of techniques to achieve-a radical suspension of judgment about the way things really are, believing that such nonjudging can be useful for challenging the unfounded dogmatism of others and may help one achieve a state of calm and tranquility.

In an introduction, Richard Bett makes the case that the most important lesson we can draw from Sextus's brand of skepticism today may be an ability to see what can be said on the other side of any issue, leading to a greater open-mindedness. Complete with the original Greek on facing pages, "How to Keep an Open Mind" offers a compelling antidote to the closed-minded dogmatism of today's polarized world.
